Composite wave absorbing metamaterials is an ideal material for wide-band radar.In this paper,a kind of composite wave-absorbing metamaterial with hexagonal ring structure is taken as an example,and the rarefaction performance of the material is analyzed by the equivalent circuit method.The results show that the rarefaction performance analysis results of the wave-absorbing metamaterial can be obtained intuitively and accurately by using the equivalent circuit method,which is more practical than the general full-wave simulation analysis method.
